(arXiv:0805.1100v2 [math-ph] UPDATED) In this paper, we develop a new method to find the exact solutions of the Einstein's field equations by using which we construct time-periodic solutions. Stefani, et al “Exact Solutions of Einstein's Field Equations”, Ch. In it the metric tensor filed g is approximated as g = η + h where η is a known exact solution to Einstein's field equations. He was a Professor of Spectroscopy analyses the exact wavelengths of light emitted by a distant star, and from the Doppler shift we are able to determine how fast they retreat from us and thus how far away they are. In particular, for the Robinson-Trautman solutions, see H. It is well known (amongst people who take an interest in physics) that Karl Schwarzschild was the first to provide a solution to Einstein's field equations for the simplest, idealised scenario of a completely symmetrical sphere in a vacuum. The Godel metric is an exact solution of the Einstein field equations, and it has closed timelike curves (CTCs), meaning that time wraps around on itself cyclically. 28, where such a set of transformations is given. The left hand side, , is called the Einstein tensor, and can be considered as representing the geometry of space-time. There is at least one solution of Einstein's field equations describing an empty universe. The essays are devoted to exact solutions and to the Cauchy problem of the field equations as well as to post-Newtonian approximations that have direct physical implications. In our universe, there In the real world we never truly have an exact diag{1,-1,-1,-1} for the metric tensor, also because we cannot "zoom in" indefinitely, i.e. Provides a number of important exact solutions which are not covered in many of the standard textbooks; Presents and proves a number of elegant theorems which have important consequences in general relativity theory; Offers mathematical Keywords » Black Holes - Einstein-Maxwell-Klein-Gordon Equations - Einstein's Field Equations - General Relativity Mathematical Approach - General Relativity Text - Newman-Penrose Formalism - Pseudo-Riemannian Space-Time Manifold. Make the neighbourhood of our point as small as we like. He was awarded the medal for his 1963 discovery of a solution to Einstein's gravitational field equations relating to black holes.
